Chemistry-Oxidation Number
NEET Chemistry Oxidation Number Match the Following Question
Type: Match the Following-match the column-Medium-Class 11
Match Column-I with Column-II.
| Column-I | Column-II |
|---|---|
| (a) Chromium | (i) +6 |
| (b) Sulphur | (ii) +4 |
| (c) Oxidant | (iii) SO 4 2– |
| (d) Reductant | (iv) SO 3 2– |
A
a-i, b-ii, c-iii, d-iv
B
a-i, b-iv, c-ii, d-iii
C
a-ii, b-i, c-iv, d-iii
D
a-iv, b-iii, c-i, d-ii
Correct Answer
Option A
Detailed Explanation
Chromium's oxidation number changes from +6 to +3, making it the oxidant, while sulphur's oxidation number changes from +4 to +6, making it the reductant. The correct pairings reflect the oxidation states and roles in the given redox reaction.
